Solar photovoltaic are extensively used as an alternative power source in gridless low grid electrified places for home lighting system such as portable lantern lighting, street lighting and home/community house lighting applications. Presently Sodium vapour(SV) lamps or CFL lamps are being used in these houses. With the advent of LED lamps which give lumen efficiencies as high as 110-140 lumen/W, the solidstate lighting is becoming a competitve technology to the conventional SV /CFL technology. The penentration of LED technology is through downsizing of the lamp size, low power requirement as compared to conventional lighting system. Besides reducing the cost of the LED lamps, major reduction in solar(PV) module cost is achieved through this downsized replacement option. Investigation study reveals that the optimization of lighting with solar powered LED lamps are feasible to meet lighting requirement in houses as well as in community placs due tto its low power consumption Thus it is concluded after investigation that solar powered LED lamps can be cost effective due to low sizing of solar pannel as compared with large sizing of conventional lamps. The study also reveals that iIts impact on indian rural society may provide potential youths an opportunity to become literate in vocational trades.
